Paper Abstract

Two approaches to visible chemical laser development are outlined. An extremely efficient near resonant intermolecular energy transfer from selectively formed metastable states of SiO and GeO to sodium atoms is used to form a sodium atom laser amplifier representing an extension of the outlined concept producing the first visible (535 nm) chemical laser amplifier and oscillator based on a thallium atom receptor. We outline the thallium laser concept and the development of the sodium based energy transfer system for laser amplification and oscillation in the wavelength ranges ~ 569 and 616 nm. In a second approach, we rely on the high cross section (pumping efficiency) highly selective and exothermic sodium trimer-halogen atom reactions to produce continuous sodium dimer laser amplifiers. Optical gain through simulated emission is demonstrated in regions close to 527 (3.8% for individual rovibronic level (? = 8 x 10-3/cm)), 492, and 460 nm (~ 2.3% for indiv. rovibronic level). Potential extensions to the ultraviolet are noted.
